Been maybe 3 years since I've had any water in this tank, but it held water just fine last time. 29G Biocube, with the MH light setup. LED's work intermittently due to the connectors having some corrosion on them. Comes with the Florescent light hood as well, but one of the ballasts popped and caused some damage to the wire, so would need some work to make useable again Comes with reservoir with water pump and air pump/stone and bag of bioballs. $100 OBO
